The drawer by her bed is only useful at 3am if the flashlight turns on, the batteries have charge, and the phone is where her hand expects it. Nobody notices those things failing until the night she reaches in, so the drawer needs a count, not a memory.

What belongs in the drawer
Keep the contents short enough to count in two minutes. That means one working flashlight, a spare set of batteries that fits it, a phone on a charger she can reach from bed, a pair of slippers or socks she can grab without bending, and a card with the numbers she calls first. Anything beyond that becomes clutter, and clutter is what gets pushed aside on the night she needs the flashlight.
Who counts, and when
Choose one person who owns the count, and write their name on the inside of the drawer or on the card, so the next person knows whose job it is. Pick a fixed day each month and do the count in the same order every time. Switch the flashlight on with the room dark. Check the batteries by how bright the beam is. Plug in the phone and confirm it is charging. Look over the cable for splits or fraying. Write down anything low before you put it back.
What to replace and what to leave alone
Replace a flashlight that dims or flickers rather than waiting for it to die. Replace batteries when the beam weakens, not when it quits. Replace a cable the day its outer sheath splits. Do not buy a new organizer to solve a missing count, because the count is the fix.
If a lamp, switch, or outlet on the route looks worn or sparks, do not wait for the monthly count. Have a licensed electrician look at it, and keep the flashlight in the drawer working until they do.
